So what is the number one expense related to a business' use of its printer? I'll give you a hint: it's not the paper.

Most offices have at least one printer and if yours is like mine, it gets a lot of use. Once you buy the thing and get it up to speed, your accountant depreciates it and your employees abuse it. But what is the number one expense related to it?

I'll give you a hint: it's not the paper. At $5 a ream or less, depending on your willingness to buy in bulk, paper (a wonderful thing to recycle, by the way!) is inexpensive. No, it's not the paper. It's the ink.

Many printer ink cartridges, while recyclable in handy mailer envelopes that come with the purchase of a new cartridge, are sorta pricey. They cost upwards of $35 each and when you consider that your staff, in spite of being told not to use printers for personal matters, are probably printing everything from church picnic fliers to their senior research paper, you need to think carefully. Is it possible you can cut costs and Greenify?

Maybe. Maybe it's as simple as changing your font.

A Dutch company, Printer.com, tested and discovered that different fonts require different amounts of ink and over the course of time, the amount of ink used, cartridges consumed, cash used and carbon footprint burned through to keep an office printer going could vary quite substantially.

The best fonts to use to ensure maximum print output for your cartridges are:

The findings showed that a someone using a home printer would use one less one cartridge per year, with the pocketed savings of about $20. But you'll also save on your carbon footprint.

Using fewer cartridges means you're printing less and printing more carefully. You're taking a step towards being more conscious of the earth and its resources. And who knows? Maybe your business correspondence will look better, too. Some of those recommended fonts are not only greener, they're very stylish!
